実験手順

The title compound was prepared by taking tert-butyl 3,4,4-trimethoxypiperidine-1-carboxylate (424 mg, 0.00154 mol) in Methylene chloride (10 mL, 0.2 mol) and adding Trifluoroacetic Acid (1 mL, 0.02 mol). The reaction was stirred for 3 h. The solvent was removed in vacuo and the crude taken to the next step (270 mg, 99%). MS calculated for C8H17NO3: (M+H) 176; found 176.1.
